So I had a problem with my previous kindle and had to return it to Amazon and I got my replacement recently. Monday morning I plugged it in via the USB chord to fully charge it. I saw an indicator light by the power switch and even heard the odd windows "external storage media connected" sound.

I left it plugged in all Monday and into Tuesday (there was no time to read Monday night so I just sort of forgot about it). Some time Tuesday day I lost power - this may or may not be relevant.

Now, the Kindle is stuck displaying the "USB Drive Mode" screen. Powering it up does nothing - no lights flash or anything. Attempting to power it down or do a hard reset does nothing. Plugging it in via USB or to a power outlet does nothing. My computer doesn't show the kindle as being attached, so there is nothing to eject.

Does anybody have any suggestions or ideas as to what happened? I am thinking I'm going to have to call Amazon again and try to get another replacement. But I thought I would ask here first.

I have also read that you should hold the switch for 30-40 seconds to force a full reboot?

This is what I would try. My K3 has been "stuck" before and I had to hold the on switch over for a very long time - probably 30 seconds. Then I let it sit for another very long time - probably 2-3 minutes before it did anything.

If it still doesn't work, I would say a call to Amazon CS is in order.

I just had that happen to me today as a matter of fact. I was using Calibre and when I ejected the Kindle it stayed in the USB mode and wouldn't do anything. I held the power button all the way for about 20-30 seconds and nothing. I plugged it back into the socket plug, held the button again and after about a minute or so it rebooted and it is fine now. scared that I would have to call customer service and get a new one. Hope that the tips that other users gave you worked for you
